Have TOOLS.md have a comparison table

[sudodoki]

There are lots of things that might be useful in table, but generally would assume

• name/tool (acting as link to homepage / repo)
• pricing / availability for commercial/educational purposes
• platform: web / desktop (stack of technologies used?)
• tasks that are supported
• doc format supported
• annotation format supported
• data import capabilities
• how export is done
• preprocessing pipeline (customizable tokenizers / etc)
• hooks / internal active learning (hinting)
• last updated date (?)

Additional useful info might be hardware required to setup tool / instructions on how use tool for specific task (done via link in specific tasks.md section)
